What does it mean that Taoism spends 33 days on its head and tramples on 18 hell?

This is not Taoism. Taoism has thirty-six floors, and Buddhism has the saying that the emperor interprets heaven in thirty-three days. The so-called thirty-three days is actually twenty days.

Besides hell, primitive Taoism may have the saying of hell-the darkest part of the underworld, see the description of evocation in Chu Ci, but eighteen layers of hell is a Buddhist saying, to be exact, it is an old Hindu saying, and Buddhism was introduced into China and blended into folklore.

When it comes to hell, it is inevitable to talk about the concept of Yan. Yan was the highest king of the underworld in ancient India. It turns out that he is a monk. After Buddhism was introduced into China, he combined with the five demons (emperors) of Han culture to create the Temple of Yan Shi, which is not an inherent view of Taoism.

When you go to Dongyue Temple, you will know that "the supervisor is divided into 36 departments and the case is sentenced to 72 Cao", which is distributed in 76 divisions, each with its own god. As for Fengdu City, influenced by various cultures, it is not easy to explore its true colors.
